This is an abridged and updated version of the award-winning publication 'Virginia's Endangered Species' (1991). An introduction summarises Virginia's natural habitats, conservation laws, and the responsibilities of the various state agencies involved in the conservation of biotic diversity in the Commonwealth. Most of the book consists of one-page descriptions and discussions of those species of plant and animal that are officially listed as endangered or threatened in Virginia. A beautiful colour photograph and map of occurrence is provided for almost every species. This guide is written in a style and format that will be enjoyed and understood by both professionals and laypersons. Its size, conciseness, and price make it an especially versatile, accessible, and useable reference and field tool for all who are interested in understanding and protecting Virginia's vulnerable natural heritage. The entries are from accounts prepared by more than 80 biologists from throughout Virginia. It contains the most current information available in printed form on the subject of vulnerable species in Virginia.
